Detailed explanation-1: -Beans are incomplete proteins because they are low in one key amino acid (amino acids are used by the body to build protein) called methionine. Cereal grains-including corn, rice and wheat-are high in methionine yet lack another amino acid found in beans.

Detailed explanation-2: -Corn, as well as most other plant-based types of protein, does have protein, but it is incomplete–lacking in a few of the essential amino acids.

Detailed explanation-3: -Neither beans nor corn alone, of course, is such a complete food because neither is a complete protein. Beans, however, contain all the essential amino acids but one, methionine, which just happens to be the amino acid that corn does have.
